Q355B is a low-alloy high-strength structural steel with a tensile strength of 470-630MPa, a yield strength of 280-420MPa, and an elongation of 21-29%. This makes it have better strength and stability under heavy loads and complex working conditions, and can show good plastic deformation ability when subjected to external forces, absorb more energy, and protect the structure from damage.
API 5L Gr.B steel pipe is a common pipeline steel pipe. API 5L Gr.B steel pipe is usually made of carbon steel and has good weldability and processability.
Made of high-quality carbon structural steel, it has been finely processed to have high strength and toughness, and can withstand the test of high pressure, high temperature and complex stress environment, ensuring the long-term stable operation of the pipeline system.
As it uses high-quality cold-rolled steel plates, the metal surface is electrostatically sprayed and treated with corresponding anti-corrosion and anti-rust processes, so the material is uniform and the performance is stable.
